ABSTRACT
Surfactants are used in many products because of their foaming properties. In foams, they spread at the interface between air and water which stabilizes the water films surrounding air bubbles. Currently, since most of the surfactants commercially used are derivatives of petroleum-based products, their replacement by biomolecules is a major issue for green chemistry. For example, the 12-hydroxy stearic acid coming from castor oil has very advantageous and original foaming properties.
